Given numbers are 871, 656, 623

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(871, 656) = 571376

GCD(871, 656) = ( 871 x 656 ) / 571376

= 871 / 656

= 871

Step2:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 871, 656, 623 is 1
